Ray tracing in Unreal Engine 4 is a powerful and flexible lighting system. It’s powerful because of its accuracy and quality. Never have you had the ability to do things like shadows and reflections like this in real time. It’s flexible because you can mix raster and ray tracing rendering features together as you see … Continued
Roughly five months ago, we introduced you to the new ray tracing support (via DirectX Raytracing) in the 4.22 release of Unreal Engine. Recently, Epic Games released version 4.23 which brings a number of upgrades for those working with ray tracing. Even better, many of these new and improved features, such as enhancements to performance, … Continued
We sat down with EPIC to discuss what Unreal Engine 4.22 brings to the table for developers.
The RTX Developer User Guide is a living knowledge document that details all the latest improvements and optimizations to ray tracing in Unreal Engine 4 (UE4).
Ray Tracing vs Rasterization Conventional 3D rendering has typically used a process called rasterization since the 1990s. Rasterization uses objects created from a mesh of triangles or polygons to represent a 3D model of an object. The rendering pipeline then converts each triangle of the 3D models into pixels on a 2D image plane. These … Continued
With real-time ray tracing, artists and designers can create cinematic-quality graphics faster than before. And now you have a chance to show us what you can design with RTX.
We talked with Andrew Harris (Studio CG Supervisor at Epic Games), Juan Cañada (Lead Programmer, Epic Games), and Juan Collado (FX Artist, Epic Games) to learn about how they are using real-time ray tracing in the production of these cinematic experiences.
In the third installment of our ‘Ray Tracing Essentials’ video series, NVIDIA’s Eric Haines touches on the decades-long history of ray tracing hardware and explains modern acceleration techniques.
We spoke with Ignacio Llamas, Director of Real Time Ray Tracing Software at NVIDIA about the introduction of real-time ray tracing in consumer GPUs. How did you get started on ray tracing at NVIDIA? I joined NVIDIA about four years ago, on the GPU architecture team. If somebody told you that you’d be shipping consumer … Continued
When you are creating triangle meshes for ray tracing or reusing meshes that have been successfully used in rasterization-based rendering, there are some pitfalls that can cause surprising performance issues. Some mesh properties that have been acceptable in rasterization can be problematic in ray tracing or require specific handling to work as expected. This post … Continued

We’ve kicked off 2019 with a free gift to the development community. Ray Tracing Gems – a cutting-edge book about ray tracing techniques – can be downloaded at no cost as a seven-part series, hosted on NVIDIA Developer Zone. The book is releasing in hardcover soon, but we wanted to give developers access to the … Continued
Ray tracing will soon revolutionize the way video games look. Ray tracing simulates how rays of light hit and bounce off of objects, enabling developers to create stunning imagery that lives up to the word “photorealistic”. This video provides an overview of how the technology works. Five Things to Remember: Ray tracing defined: a primitive … Continued
At GDC 2019, NVIDIA’s Martin Stich walked attendees through ray tracing in 4A’s Metro: Exodus (available now) and Remedy’s Control (coming later in 2019) on PC.
In 2018, with the release of NVIDIA’s RTX series GPUs, real-time ray tracing finally became accessible to game developers, content creators, and consumers. It is a technology that will forever change graphics processing. To help developers navigate this new technology, a wide-ranging book on the topic is being published early this year: Ray Tracing Gems. … Continued
